hi,
my problem is a more generell problem. i am asking here to find out, if
there is a special angularjs feature, which reduces the complexity of a for
loop with promises.
a short example:
i got a function surrounded by a $q. in this function, a code is iterated
through a for-loop. if the value of the code is "0", continue with the next
step in the for-loop. otherwise, go through some other asynchronous service
functions to set the variable myData correctly.
return $q(function (resolve, reject) {
var pCode = "1050";
var myData = {};
for (var i = 0; i <= pCode.length; i++) {
var lcHumanIdx = i + 1;
if (pCode[i] === "0") {
continue; i = i + 1;
} else {
if (lcHumanIdx === 1) {
SomeService.asyncFunction(pCode[i])
.then(function (pElement) {
if (pCode[i + 1] !== "-") {
myData.translation = pElement;
} else {
OtherService.asyncFunction()
.then(function (pOtherElement) {
myData.translation = pOtherElement;
})
}
...
resolve(myData);
// or handling with many promises
// $q.all(collectedPromises).then(function() {
console.log("Done"); })
});
before i go and code, i just wanted to ask, whats the best practise to
realize such a problem. are there any specific angularjs solutions (like
bluebirds promiseWhile/-For)? the problem in this example is, that the
variable myData is {} every time! the variable is resolved before the
asyncronous functions completed. my aim is to set all "attributes" of
myData (f.e. myData.translation) correct, and then resolve it. what would
be the best realization?
